I have a iPhone 3GS that I accidentally updated to 6.1.3 and now I can't used the envasi0n jailbreak. Every time I try to downgrade it gives me the 3194 error message in Itunes. I've tried the thing where you go to C:/Windows/System32/drivers/etc/ and I don't see the line 74.208.105.171 gs.apple.com line. Please help! Thanks! I'm looking for a untethered options.
